The Naucoridae (Heteroptera: Nepomorpha) of Belize

Few regional faunistic treatments of aquatic Heteroptera exist for Mesoamerica. Records given here are the result of three extensive, coincident projects, each generating many specimens of Naucoridae. Thus, presented here is an annotated list of Naucoridae occurring in Belize, with an illustrated taxonomic key and notes on habitat. Three species are new country records, and ten species in four genera are now known from Belize
